Activiti import file from Bizagi Modeler

Hi everybody,I don't know if this is correct node in forum where I can ask, in this case sorry me, and move in correct node please. So I expose my problem.. I need to import some file with extension .bpm or .bpmc that are builded with Bizagi Modeler, but at the moment it's not possible. The schema of those files are different from actual schema that is in Activiti. So what I have to do? Writing my own parser for these files?
